Day by day
Stage 4: Puigcerdà-La Seu d'Urgell. This is not a very long stage, but it is really challenging. The goal is reaching Port d'Envalira, 2407 mts, the highest asphalted pass of whole Pyrenees (understanding pass as a climb between two valleys, not a "cul de sac" climb). Long and fast descent to Andorra, the buyers paradise, and arrival at La Seu d'Urgell.
Stage 6: Esterri d'Aneu-Bagneres de Luchon. Two very different but both demanding climbs: La Bonaigua is a long ascent, over 2000 mts high, long but steep. Portillon is the pass connecting Spain to France, short and very steep. Arrival to France. We are getting closer the final challenge.
Stage 7: Bagneres de Luchon-Tourmalet. Just 77 km, but such an epic stage. History of Tour de France was written here. The trilogy Peyresourde-Aspin-Tourmalet has been a classic in Tour de France. Tourmalet is the final destination of our trip, the final challenge. After reaching the summit you can descend by bike or in the van, as you already got the end of the trip. This night you will sleep again in Bagneres de Luchon where you can have a relaxing bath in the thermal baths of the town. Deserved.
